Hi David, As a first shot, try deleting any .ycr and .yca files you have sitting around - the format changed recently which can result in these invalid binary data messages. Thanks Neil On 6/2/07, David Fox wrote:

Hi,

I have fixed the Javascript backend to accomodate the new type layout in Core (primitives and functions got an unified type).

Changes have been pushed to the repo. No new functionality was added. At least this demo program:

http://www.golubovsky.org/repos/hibb/EchoCPS.hs

compiles to this web page:

http://www.golubovsky.org/repos/hibb/EchoCPS.html

Those who experiment with the Javascript backend please try compiling your programs and let me know if anything went broke.

Thanks.

Aha! My build procedure has a flaw. After I build the new compiler I go into src/translator/js and build there, but the Makefile in there uses the old compiler. I had to add YHC=$(CURDIR)/inst/yh YHC_BASE_PATH=$(CURDIR)/inst to the make arguments. On 6/2/07, David Fox wrote:

I'm pretty sure it is related to the UnsafeJS.ycr file produced by the new compiler. I did an strace and the error occurred right after reading /usr/lib/haskell/UnsafeJS.ycr, which was built during the build of the new compiler. When I copy UnsafeJS.hs into my working directory and compile, the crash comes right after reading the just compiled local file ./UnsafeJS.ycr.

Please make sure you regenerated _ALL_ ycr files that might have existed before the core format/version upgrade. This error is caused by the deserializer when it encounters a core file with older version. -- Dimitry Golubovsky Anywhere on the Web
